| RESULTS : To identify new ERBIN binding proteins , we screened a yeast two hybrid library , using the carboxyl terminal fragment of ERBIN containing PDZ domain as the bait , and we isolated p 0071 ( also called plakophilin 4 ) as an ERBIN interacting protein . p 0071 is a member of the p 120 catenin family , which are defined as proteins with 10 armadillo repeats , and localizes along the cell cell border . ^^^ |
